You can choose from the following soil organism tests:

OECD 207

Earthworm acute toxicity test

This test evaluates the acute toxicity of your chemical on earthworms. Earthworms are exposed to treated soil in a range of concentrations to assess the effects upon mortality and weight.

OECD 222

Earthworm reproduction test

This test assesses the effects of your chemical in the soil on the reproductive output of earthworms. Adult worms are exposed to a range of concentrations of the test substance, and their behaviours and morphology observed over a set period. The number of juveniles hatched is also measured. The reproductive output of the test worms is compared to that of a control group.

OECD 216

Nitrogen transformation test

This test investigates the long-term effects of chemicals, after a single exposure, on the nitrogen transformation activity of soil microorganisms. Soil is mixed with your product and samples are taken at intervals throughout the test period. The nitrate transformation rate is determined, and compared with untreated control samples.

OECD 226

Predatory mite reproduction test

This test assesses the effects of your chemical in the soil on the reproductive output of soil mites. Adult female mites are exposed to a range of concentrations of test substance for a set period. The numbers of surviving adults and juveniles is determined. The reproductive output of the test mites is compared to that of a control group.

OECD 232

Collembolan reproduction test

This test assesses the effects of your chemical in the soil on the reproductive output of collembolans. Adult collembola are exposed to a range of concentrations of test substance for a set period. The numbers of surviving adults and juveniles is determined. The reproductive output of the test mites is compared to that of a control group.
